OVERVIEW
AIN16-C-2 Analog Input Module is a module which has 16 channels of 4mA-20mA sensor input and 3 channels of speed sensor input. The 4mA-20mA data and speed data are transmitted to the master controller for processing via RS485 port. Different alarm threshold values can be set for each sensor via master controller.
PERFORMANCE AND CHARACTERISTICS
- With 32-bit ARM based SCM, high integration of hardware and more reliable;
- Must be used with master controller together;
- RS485 communication baud rate can be set as 9600bps or 19200bps via dial switch;
- Module address can be set as 1 or 2 via dial switch;
- Wide power supply range DC(18~35)V, suitable to different battery voltage environment;
- 35mm guide rail mounting type;
- Modular design, pluggable terminal, compact structure and easy installation.

| SYMPTOMS | POSSIBLE CAUSES | COMMENTS |
| • Noisy Pump | – Seized pump. – No water in the network. – Obstruction in water supply. | – If the water has particles suspended in it or is too hard, you should install a water softener filter. |
| • Slow dispensing, burnt coffee. | – Incorrect calibration of the pump. Pump with reduced draught | – Check the pump pressure with a gauge. |
| • Slow dispensing. • Burnt and cold coffee. • Dark cream with a tendency to be porous. • Continuous coffee dispensing suddenly stops and the ‘no water indicator blinks. • One-coffee and two-coffee lights blinking. | – Grinding point too fine. – Low pump pressure. – Injector filter dirty, partially obstructed. – Low water level in reservoir – Volume counter does not work correctly. – Coffee is excessively fine or there is no water. | – If they are blinking and to know whether it is due to the coffee, or due to a lack of water or due to the volume counter, take out the filter holder and press the button. If the blinking continues and water has come out, it may be due to the volume counter. |
| • Electronic machines: One-coffee, two-coffee keys and LED level indicator blinking. • Semi-automatic machines: Boiler Water Level indicator is blinking. | – Boiler Water Level alarm has been activated. | – Check that the main water valve is open or that there is water in the internal tank (according to version). The warning will disappear once the machine is turned off and tumed on again. |
